We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are ...

A vehicle’s Check Engine light can turn any car ride into a harrowing experience. As soon as the check engine light ...

Abstract: Wire retention force is an important indicator for evaluating the reliability of wire insertion in electrical connectors. Current approaches to measure this force are mainly relied on spring ...

The Oura Ring 4 will cost $349 for Silver or Black, $399 for Brushed Silver or Stealth, or $499 for Gold or Rose Gold. In ...

Abstract: This study presents an innovative approach to early detection of wire bond lift-off failures in power semiconductor modules (PSMs) using an integrated on-chip temperature sensor. Despite ...

I tested six popular thermometers and compared their ease of use, reading speed and design, and found two models I’d recommend to anyone for at-home use.

The Time of Flight (ToF) sensor is significantly more accurate than the ultrasonic sensor. This is evident through the data shown above. Although the measurements were generally smaller than realistic ...

Cardiac device therapy has significantly evolved since the introduction of the first implantable pacemaker and the subsequent ...

The iconic sleep-tracking smart ring is accurate and comfortable—but smart rings make poor activity trackers.

To find the right circuit in the electrical panel, you first plug the socket tester into a socket. Then you go to the panel and slide the probe up and down all the breakers. You then do a complete ...
